According to the law of multiple proportions: A) the total mass is the same after a chemical change as before the change. B) it is not possible for the same two elements to form more than one compound. C) the ratio of the masses of the elements in a compound is always the same. D) if the same two elements form two different compounds, they do so in the same ratio. E) none of these

As per this law, if the same two elements form two different compounds, they do so in the same ratio. The correct option is D.

What is law of proportion?

The law of multiple proportions in chemistry states that if two elements combine to form more than one compound, the ratios of the masses of the second element that combine with a fixed mass of the first element will always be ratios of small whole numbers.

When working with compounds containing more than two elements, the law operates in the same manner.

Choose a 100-gram sample (so you're dealing with percentages) and divide the largest mass by the smallest mass to simplify the calculation.

Because a real constant can always be expressed as the ratio of two whole numbers, the Law of Multiple Proportions was born.

Thus, the correct option is D.
